A witness at a glass company near the Navy facility said the area was on lockdown, with the shooting starting at about 11 a.m.
"We have heard multiple shots fired," said Marilyn Hutcheson of Binswanger Glass installation and repair service. "It's very scary ... right now it's a very fluid situation," she said.
Lee University, in Cleveland Tennessee, about 30 miles (50 km) to the northeast, was on lockdown, the school said on its website. It advised people to stay inside until further notice.
